Patented Oct. 28, 1952 Charles--A.-Pressnall, Elkhart, Ind., assignor to The Adlake Gompany,.Chicago, 111., a. corporation of. Illinois 7 jApp licationJune 10, 1947, Serial No. 753,644 I 6Claims. (01. 189-76) This invention is concerned with improveme in window sash construction.

It is an object of the invention to provide a window sash construction of the type which is particularly adapted to be made of metal, such as extruded aluminum sections, having improved means for securing the end of the balance tape to the vertical side frame member of the sash.

It is a more specific object of the invention to' provide a metal window sash construction having a stainless steel plate adapted to be secured to the upper corner of the sash and provided with a hook or tongue portion extending downwardly along the side frame member of the sash constituting an anchoring means for detachably receiving the end connecting member of a balance tape.

These and other objects of the invention will be apparent from a description'of the preferred form thereof which is shown by way of illustration in the accompanying drawings, wherein:

Fig. 1 is a perspective view of an upper corner of a sash having incorporated therein a construction embodying the principles of the invention;

Fig. 2 is an exploded view showing in perspective the corner of the sash, the depending end of a balance tape and the anchor plate for securing the end of the tape to the sash;

Fig. 3 is a side elevation of the corner of the sash with portions of the weather strip member broken away; and

Fig. 4 is a section on the line 4-4 of Fig. 3.

The sash illustrated in Fig. 1 is a portion of a lower sash which is adapted to be mounted in the frame of either a single hung or double hung sash type window. While a lower sash is illustrated, the principles of the invention may be applied to an upper sash in the same manner.

The top horizontal rail member ID of the sash is secured at its end in abutting relation to the vertical side member H to form the corner joint. The members In and II may be secured to each other by bolts or similar fastening means.

The vertical side member I I comprises a front plate or flange member l2, a rearwardly extending web member l3 and a rear flange member l4, preferably formed integrally as an extruded metal section.

The front member 12 is provided at its inner edge with an inwardly directed flange [5 (Fig. 4) which forms one side of the glazing channel for the glass pane (not shown). The inner edge of the rear flange member l4 extends only to the web member l3 and is there provided with a thickened portion l6 having a relatively narrow 2 inwardly opening, vertically extending groove' l'l for receiving the glazing beadfnot shown) which secures the pane in the glazing channel.

The front flange member I2 is provided adja: cent its outer edge with a forwardly facing, vertically extending channel-like recess or groove l8 and'the rear flange member I4 is provided ad acent its outer edge with a similar groove 19 which faces rearwardly.

A weather strip channel member 20 having parallel legs 2| and 22 is provided, on its outer surface, with a non-metallic weather strip 23, the edges of which are secured to the channel-member 20 by bead-like formations 24 and 25,p ro; vided by curling outwardly the edges of the legs 2| and 22. The weather strip member is mounted on the vertical sash member I by positioning the bead formations 24 and 25 in the parallel grooves l8 and I! of the sash member.

Transversely aligned slots 26 and 21 are provided a short distance from the top of the sash by cut-out portions in the outer edges of the members l2 and I4 for a purpose which will be described.

A- tape end anchor member 28 is provided which is preferably made of stainless steel plate. It is cut and shaped to provide'a relatively wide top or horizontal portion 29 and a relatively narrow integral leg portion 30 which extends downwardly of the top plate 29 and terminates in an outwardly offset tongue or hook portion 3 I. The top plate 29 is of a size sufficient to cover the top of the vertical sash member H" and to extend a short distance over the top surface 32 of the rail member Ill. The leg portion 30 is of a width which adapts it to be positioned in the channel or groove formed betweenthe inner surfaces of the flange members I2 and I4 and is provided adjacent its lower end with lateral extensions 33 ane'sa which fit into the transversely aligned slots 26 and 21 in the edges of the flange members l2 and H. The offset portion 35 connecting the leg 30 and the hook'3l forms a shoulder which is engaged by' the apertured attaching member 36 on the end of the balance tape 31 when the members are inassembled relation as inFig. l.

The anchor member 28 is retained in position by the engagement of the lateral extensions 33 and 34 in the transverse slots 26 and 21 and the tension in the balance tape 31. As anadditional means for securing the anchor member 28 to the sash it is preferred to provide an aperture 38in the top plate member 29 and a threaded aperture 39 in the rail member l0 for reception of a securdesired manner against downward movement. f

The anchor plate 28 is disengaged from the sash by removing the securing screw 40 and moving plate 28 outwardly to free the lateral extensions 33 and 34 from the slots 26v and 21. whereupon the end of the balance tape 31 is released. The weather strip carrying channel may also be removed vertically of the sash since the bead formations 24 and 25 are slidably positioned" in the grooves l8 and I9.

While specific materials and details of construction have been referred to, it will be under.- stood that other materials and details of construction may be resorted to within thespirit of the. invention.
